Forms

confirmer[1] Old and Middle French usually confermer, frequent until the 16th century and still recorded by Cotgrave in 1611.[2][3] Anglo-Norman spellings include cunfermer and confirmer.[4]

Etymology

It is borrowed from Latin cōnfirmō (“to strengthen, establish, assure”), formed from cum and firmus (“firm, steady”), and in Christian Latin a liturgical term.[2][3][5] The common old form confermer was replaced by the present form, remade on the Latin.[2][3] Wiktionary instead derives the word from the Middle French form.[1]

Cognate with Occitan confirmar, Spanish confirmar and Italian confirmare.[6] It is related to French ferme1 and fermer.[5][7]

Earliest recorded meaning

It is first found in the 10th-century Passion, in confirmer en veritad, to assure someone that he is in the truth.[2][3][8]

Semantic evolution

Of a person, the verb meant “to strengthen” (mid-12th century, the Cambridge Psalter), now a literary use.[2][3] From about 1174 it was also the liturgical term for giving the sacrament of confirmation.[2][3] Of things it was first legal or official, “to ratify” laws or charters (about 1174, Guernes de Pont-Sainte-Maxence), and spread to “to establish more firmly as true”, often in the pronominal la nouvelle se confirme (Richelet, 1680) and the passive.[2][3]

The proverb l'exception confirme la règle keeps the old sense “to strengthen”.[7]
